CROSS REFERENCE TO RELATED APPLICATIONS

The instant non-provisional patent application claims priority from provisional patent application No. 62/241,587, filed on Oct. 14, 2015, entitled MAGNETIC SLEEPING BAG, and incorporated herein in its entirety by reference thereto.

BACKGROUND OF THE INVENTION

Field of the Invention

The embodiments of the present invention relate to a sleeping bag, and more particularly, the embodiments of the present invention relate to a sleeping bag for providing easy and carefree exit and entry for a user, for providing comfort for the user by having an ability to selectively extend appendages of the user out of the sleeping bag without having to open the sleeping bag in its entirety, and for providing a no-fail engage/disengage exit for potential emergency situations.

Description of the Prior Art

A sleeping bag is an insulated covering for a person, essentially a lightweight quilt that can be closed with a zipper or similar apparatus to form a tube, which functions as a lightweight and portable bedding in situations where a person is sleeping outdoors, e.g., when camping, hiking, hill walking, or climbing.

The sleeping bag's primary purpose is to provide warmth and thermal insulation through its synthetic or down insulation. It also typically has a water resistant or water repellent cover that protects - to some extent - against wind chill and light precipitation. The bottom surface also provides some cushioning and may be moderately water repellent.

There are a range of sleeping bag models designed for different purposes. Very lightly insulated sleeping bags are designed for summer camping use or for indoor use by children during slumber parties. Well-insulated bags are designed for cold weather use.

The most well-insulated and lightweight sleeping bags—which are designed for serious hikers and adventurers—are more expensive than lightly insulated sleeping bags. One subcategory of cold-weather sleeping bag, the mummy bag, is so named because it has an insulated hood for the head. A bivouac sack (bivy) is a waterproof cover for a sleeping bag that may be used in place of a tent by minimalist and experienced hikers. A bivy bag may also be carried by day hikers as a backup or emergency shelter to be used if they cannot make it back to their starting point by nightfall due to inclement weather or getting lost.

The state of the sleeping bag art has many drawbacks, a few include:

1. Doesn't provide easy and carefree exit and entry for a user;

2. Provides less comfort for the user by not having an ability to extend appendages of the user out of the sleeping bag without having to open the sleeping bag in its entirety;

3. Does not provide a no-fail engage or disengage exit for potential emergency situations;

4. Zipper mechanism may jam upon entry and exit.

Numerous innovations for sleeping bags have been provided in the prior art, which will be described below in chronological order to show advancement in the art, and which are incorporated herein in their entirety by reference thereto. Even though these innovations may be suitable for the specific individual purposes to which they address, nevertheless, they differ from the embodiments of the present invention, in that they do not teach a sleeping bag for providing easy and carefree exit and entry for a user, for providing a no-fail closure mechanism comprised of alternating polarity magnets on each strip, for providing comfort for the user by having an ability to selectively extend appendages of the user out of the sleeping bag without having to open the sleeping bag in its entirety, and for providing a no-fail engage/disengage exit for potential emergency situations.

No. 4,894,878—issued to Roach on Jan. 23, 1990 in US class 5 and subclass 413R—teaches a sleeping bag including an outer shell, an inner liner, and a plurality of longitudinally extending insulating batts therebetween secured along their longitudinal edges to the shell and to the liner in an overlapping and shingled arrangement. The circumferential dimension of the liner can be reduced by connecting spaced-apart zipper elements fastened to the liner, thus causing an increased overlap of the batts resulting in increased thermal insulation. A cord casing at the head hole is secured to the liner along a line spaced-apart from the seam joining the shell and the liner at the head hole, so that when the draw string is pulled taut, creasing and other deformation of the shell surrounding the head hole is minimized so to reduce any decrease in thermal insulation. The head and foot of the bag define three dimensional cavities sized to generally conform to the user's head and feet to minimize compression of the bag. The access zipper extends beneath the user to minimize heat loss.

U.S. Pat. No. 8,707,479 to Benninger

U.S. Pat. No. 8,707,479—issued to Benninger on Apr. 29, 2014 in US class 5 and subclass 413R—teaches a sleeping bag constructed so that its outer circumference is greater than its inner circumference. The bag includes additional integrated protuberances, or space fillers, that are added to the interior lining of the sleeping bag to fill-in around the sleeper's body. Making the circumference of the outside of the bag greater than the inside maintains the thickness of the insulation in selected areas. To maintain insulation thickness at other locations around the sleeper's body, the insulation-containing space fillers are incorporated into the interior of the bag and expand under the influence of the insulation to fill-in around the sleeper for reducing the internal volume of the bag. This construction can be carried the length of the sleeping bag.

It is apparent that numerous innovations for sleeping bags have been provided in the prior art, which are adapted to be used. Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, nevertheless, they would not be suitable for the purposes of the embodiments of the present invention as heretofore described, namely, a sleeping bag for providing easy and carefree exit and entry for a user, for providing comfort for the user by having an ability to selectively extend appendages of the user out of the sleeping bag without having to open the sleeping bag in its entirety, and for providing a no-fail engage/disengage exit for potential emergency situations.

Thus, there exists a need for a sleeping bag for providing easy and carefree exit and entry for a user, for providing comfort for the user by having an ability to selectively extend appendages of the user out of the sleeping bag without having to open the sleeping bag in its entirety, and for providing a no-fail engage/disengage exit for potential emergency situations.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Introductory

Referring now to the figures, in which like numerals indicate like parts, and particularly to FIG. 1, the sleeping bag of the embodiments of the present invention is shown generally at 10 for providing easy and carefree exit and entry for a user, for providing comfort for the user by having an ability to selectively extend appendages of the user out of the sleeping bag 10 without having to open the sleeping bag 10 in its entirety, and for providing a no-fail engage or disengage exit for potential emergency situations.

The sleeping bag 10 provides safe and easy operation for users who are children and the disabled.

Overall Configuration of the Sleeping Bag 10

The sleeping bag 10 comprises a lower layer 12, an upper layer 14, and a magnetic closure 16. The upper layer 14 overlies the lower layer 12 so as to form a user space 18 therebetween for a user. The magnetic closure 16 replaceably attaches a portion 20 of the upper layer 14 to a corresponding portion 22 of the lower layer 12 for providing the easy and the carefree exit and the entry for the user, for providing the comfort for the user by having the ability to selectively extend the appendages of the user out of the sleeping bag 10 without having to open the sleeping bag 10 in its entirety, and for providing the no-fail engage/disengage exit for the potential emergency situations.

The magnetic closure 16 replaces a zipper closure of a conventional sleeping bag.

Specific Configuration of the Lower Layer 12

The lower layer 12 is for resting on a support surface 24, is insulated for maintaining a desired temperature in the user space 18, and is waterproof for protection if the support surface 24 is wet.

The lower layer 12 has a perimeter 26. The corresponding portion 22 of the lower layer 12 is a part of the perimeter 26 of the lower layer 12.

The perimeter 26 of the lower layer 12 is generally rectangular-shaped, and as such, has a pair of long edges 28 and a pair of short edges 30.

The corresponding portion 22 of the perimeter 26 of the lower layer 12 includes one short edge 30 of the perimeter 26 of the lower layer 12 and an adjacent long edge 28 of the perimeter 26 of the lower layer 12.

The corresponding remaining portion 40 of the perimeter 26 of the lower layer 12 includes the other short edge 30 of the perimeter 26 of the lower layer 12 and the other long edge 28 of the perimeter 26 of the lower layer 12.

Specific Configuration of the Upper Layer 14

The upper layer 14 is insulated for maintaining a desired temperature in the user space 18, and overlies the lower layer 12 to define the user space 18 therebetween.

The upper layer 14 has a perimeter 32. The portion 20 of the upper layer 14 is a part of the perimeter 32 of the upper layer 14.

The perimeter 32 of the upper layer 14 is generally rectangular-shaped, and as such, has a pair of long edges 34 and a pair of short edges 36.

The upper layer 14 overlies the lower layer 12 and a remaining portion 38 of the perimeter 32 of the upper layer 14 is affixed to a corresponding remaining portion 40 of the perimeter 26 of the lower layer 12, with the portion 20 of the perimeter 32 of the upper layer 14 and the corresponding portion 22 of the perimeter 32 of the lower layer 12 being normally open for the user 18, but selectively closed by the magnetic closure 16.

For clarity, the corresponding remaining portion 38 of the perimeter 32 of the upper layer 14 is the perimeter 32 of the upper layer 14 minus the portion 20 of the perimeter 32 of the upper layer 14, and the corresponding remaining portion 40 of the perimeter 26 of the lower layer 12 is the perimeter 26 of the lower layer 12 minus the corresponding portion 22 of the perimeter 32 of the lower layer 12.

The corresponding portion 22 of the perimeter 26 of the lower layer 12 includes one short edge 30 of the perimeter 26 of the lower layer 12 and an adjacent long edge 28 of the perimeter 26 of the lower layer 12.

The corresponding remaining portion 38 of the perimeter 32 of the upper layer 14 includes one short edge 36 of the perimeter 32 of the upper layer 14 and an adjacent long edge 34 of the perimeter 32 of the upper layer 14.

Specific Configuration of the Magnetic Closure 16

The specific configuration of the magnetic closure 16 can best be seen in FIG. 2, and as such, will be discussed with reference thereto.

The magnetic closure 16 comprises a pair of material strips 42. Each material strip 42 of the magnetic closure contains consecutive magnets with alternative polarity 16 forms a generally L-shape, and is flat. One material strip 42 of the magnetic closure 16 extends along the corresponding portion 22 of the lower layer 12. The other material strip 42 of the magnetic closure 16 extends along the portion 20 of the upper layer 14, in ideal alignment with the one material strip 42 of the magnetic closure 16 due to the lining up of alternative polarity of each strip 42.

The magnetic closure 16 further comprises a pair of a plurality of magnets 44, and are, preferably, disk-shaped, and made from high strength neodymium.

One plurality of magnets 44 of the magnetic closure 16 extend along the one material strip 42 of the magnetic closure 16 and are spaced thereapart, while the other plurality of magnets 44 of the magnetic closure 16 extend along the other material strip 42 of the magnetic closure 16 and are spaced thereapart.

The one plurality of magnets 44 of the magnetic closure 16 are spaced apart from each other a distance equal to a distance that the other plurality of magnets 44 of the magnetic closure 16 are spaced apart from each other for proper engagement when the magnetic closure 16 is closed.

As shown on FIG. 2, adjacent ones of each of the pair of plurality of magnets 44 of the magnetic closure 16 have opposite polarities so as to provide alternating polarities of each of the pair of plurality of magnets 44 of the magnetic closure 16 for assuring a uniform closure of the magnetic closure 16. For example, one magnet is positive, while the magnet directly adjacent thereto is negative. As further shown on FIG. 2, a distance between adjacent ones of the pair of plurality of magnets 44 of the magnetic closure 16 is proportional to magnetic strength of the pair of a plurality of magnets 44 of the magnetic closure 16 for preventing adjacent ones of the pair of plurality of magnets 44 of the magnetic closure 16 from being attracted to each other, especially in view of the opposite polarities of the adjacent ones of the pair of plurality of magnets 44 of the magnetic closure 16.

The magnetic closure 16 further comprises stitches 46.

The stitches 46 of the magnetic closure 16 hold the one material strip 42 of the magnetic closure 16 to the corresponding portion 22 of the lower layer 12 and hold the other material strip 42 of the magnetic closure 16 to the portion 20 of the upper layer 14.
